If the pump performance does not satisfy your process requirements, and the process requirements
have not changed, then perform these steps:
1.
Disassemble the pump.
2.
Inspect it.
3.
Replace worn parts.
6.2 Bearing maintenance
These bearing lubrication sections list different temperatures of the pumped fluid. If the pump is
ATEX-certified and the temperature of the pumped fluid exceeds the permitted temperature values, then
consult your ITT representative.

Ring oil
Purge oil
Add oil before you install and start the
pump. Change the oil and oil filter after
200 hours for new bearings.
After the first 200 hours, change the oil filter every 2000
operating hours and the oil every 6000 operating hours. If
you do not change the oil filter as recommended, oil must
be changed every 2000 hours.
Pure oil
Forced oil
Follow the recommendations from the
manufacturer.
Follow the recommendations from the manufacturer.
6.3 Mechanical-seal maintenance
WARNING:
The mechanical seal used in an Ex-classified environment must be properly certified.
CAUTION:
Running a mechanical seal dry, even for a few seconds, can cause seal failure and physical
injury. Never operate the pump without liquid supplied to the mechanical seal.
Cartridge-type mechanical seals
Cartridge-type mechanical seals are commonly used. Cartridge seals are preset by the seal manufactur-
er and require no field settings. Cartridge seals installed by the user require disengagement of the hold-
ing clips prior to operation, allowing the seal to slide into place. If the seal has been installed in the pump
by ITT, these clips have already been disengaged.
Other mechanical seal types
For other types of mechanical seals, refer to the instructions provided by the seal manufacturer for instal-
lation and setting.
Reference drawing
The manufacturer supplies a reference drawing with the data package. Keep this drawing for future use
when you perform maintenance and seal adjustments. The seal drawing specifies the required flush fluid
and attachment points.
